As Akira was observing Amano Yuuma, Amano Yuuma was also sizing him up.
[Is this the person Lord Azazel asked me to collect data on?]
[He looks quite handsome, but unfortunately, he's too weak.]
[Well, I'll just finish collecting his bodily fluids data quickly~]
To complete the mission assigned by her superiors, Amano Yuuma decided to take a bold approach.
...
"Um! Even though Akira-san doesn't know me, I've known about Akira-san for a long time!"
As she spoke, a charming blush spread across Amano Yuuma's cheeks.
"You know me?"
Akira wasn't sure which version of himself Amano Yuuma was referring to.
"That's right! Akira-san, I know you. You're the top student in your year at Kuoh Academy, and you're quite famous in other schools too~" Amano Yuuma brushed her hair behind her ear, perfectly portraying the image of a shy, reserved girl who wanted to show her best side.
"So, Miss Amano Yuuma, what brings you to me?" Akira asked.
"Akira-san... I came to confess my feelings!" Amano Yuuma put on the appearance of a girl mustering up the courage to confess.
"I... I really like Akira-san..."
"Akira-san, would you please go out with me?!"
With that, Amano Yuuma looked up and rushed toward Akira.
The innocent black-haired beauty wrapped her arms around Akira's neck and pressed her lips to his.
...
Akira didn't resist.
Coincidentally, he wanted to conduct an experiment.
Lately, he had noticed that the blonde maid at home had been looking at him strangely.
Late at night, she would leave her room door open while using silent water magic, calling out his name as she did so.
During the day, after meals, the blonde maid would collect his utensils and even lick his spoon.
Every time he finished bathing, his underwear would already be taken away by her.
So, Akira wanted to use Amano Yuuma as a comparison.
He wanted to find out.
Was it his succubus bloodline awakening? Or was the maid at home just a perverted stalker?
...
Amano Yuuma's violet eyes were filled with tenderness, and her arms unconsciously tightened around Akira, as if trying to merge him into her body.
"Mmm... mmm..."
She couldn't help but lose herself in the moment.
A few minutes later, Akira gently pushed Amano Yuuma away.
Looking at her dazed expression and flushed cheeks, Akira had reached a conclusion.
It seemed his succubus bloodline had indeed awakened.
...
"I-I'm sorry, I just like Akira-kun so much..."
Amano Yuuma lowered her blushing face.
She was genuinely embarrassed.
She didn't know what had come over her, but she had unconsciously responded and matched Akira's actions.
Wasn't she just supposed to collect his bodily fluids data?
Seeing Amano Yuuma's reaction, Akira nodded in satisfaction.
He had already reached his conclusion.
"It's fine, I like Yuuma-chan too. From today on, we're in a relationship."
"As your boyfriend, can I do it again?"
Akira's experiment had entered its second phase.
"I..."
Amano Yuuma hesitated.
She instinctively wanted to accept.
But something felt off.
Akira smiled and, while Amano Yuuma was still hesitating, gently lifted her smooth chin.
This time, Akira took the initiative.
A few minutes later, Amano Yuuma's body felt weak, her gaze soft, as if she had become a completely different person.
"Yes! Akira-kun, since we both feel the same way, let's start dating~"
Amano Yuuma looked at Akira with hopeful eyes.
This had nothing to do with her mission.
She genuinely wanted to be with Akira.
This feeling was intoxicating.
Her intimate contact with Akira reminded her of the reason she had fallen from heaven.
Wasn't this the kind of freedom and joy she had been seeking?
...
"Yuuma-chan, as your boyfriend, I'll be counting on you from now on."
With the experiment complete, Akira hugged Amano Yuuma.
The girl's refreshing scent was comforting to Akira.
It was a mix of innocence and allure, perfectly embodying Amano Yuuma's unique charm.

[Ding!~]
[Congratulations, host, for completing the Villain Check-in!]
[Check-in Level: Purple.]
[Check-in Type: Event Check-in.]
[Check-in Event: First Love Acquired.]
[Congratulations, host, for receiving the reward: Secret Sword Technique.]
[Secret Sword Technique: A technique derived from Ikki Kurogane's secret sword skills, consisting of seven powerful moves that can adapt to almost any combat situation.
The host's Secret Sword Technique is no longer limited to swords. Even without a sword, using claws or even just the body, the host can unleash the essence of the Secret Sword Technique.]
"The Secret Sword Technique is quite a powerful skill."
"However, compared to sword skills, I'd rather enhance my own strength."
Demons are a race that relies on vast amounts of magical power and various magical traits to overpower their enemies. Akira wasn't particularly interested in sword techniques.
Of course, having it was better than not.
He couldn't rely solely on long-range attacks, so learning some close-combat skills was necessary.
In the original story, Diodora had prided himself on his immense magical power, only to be crushed by the original protagonist's Balance Breaker.
Overpowering with brute force? Could it compare to the Red Dragon Emperor's overwhelming strength?
...
After that, it was time for their date.
Amano Yuuma had originally planned to kiss him and leave, purely for the mission.
But now, she was on a date with Akira.
Because she couldn't refuse his requests.
The two visited many places.
A café.
Amano Yuuma watched Akira's used straw and couldn't help but swallow hard.
A lingerie store.
Amano Yuuma pulled Akira into the fitting room, asking him to pick out his favorite styles.
A movie theater.
The dim lighting suited Amano Yuuma's mood perfectly, and she sat reversed in her seat, engaging in intimate exchanges with Akira.
Finally, at the clock tower.
Under the breathtaking sunset, Amano Yuuma, filled with girlish emotions, embraced Akira, engaging in a passionate exchange that lasted half an hour.
"Akira-kun!~ Let's meet again tomorrow after school for another date~"
Amano Yuuma waved goodbye with a smile.
Today, she was more than satisfied.
Akira watched Amano Yuuma's departing figure, then looked at his own hand.
"I wonder when my succubus bloodline awakened."
"It was supposed to be just a trace, so why is the effect so overpowering?"
"Maybe I've been going in the wrong direction from the start?"
"If I had made Serafall fall for me when I was a child, I could've been living off the Demon King's wealth by now."
After sighing, Akira turned his gaze to a dark corner of the street.
"You've been watching for a while now, haven't you? Why don't you come out and show yourself?"
As soon as he finished speaking, a blonde young man stepped out of the shadows.
"Akira Leviathan, what did you do to the fallen angel's boss?"
The blonde young man raised a gun, ready to shoot at a moment's notice.
This gun could fire light bullets that were effective against demons, a standard weapon for church priests.
"Freed..."
Akira narrowed his eyes, calling out the blonde priest's name.
[Ding!~]
[Congratulations, host, for triggering a Villain Check-in!]
[Check-in Level: Purple.]
[Check-in Type: Event Check-in.]
[Check-in Event: The Fallen Priest's End.]
[Requirement: Kill the fallen priest Freed, eliminating the risk of your high-dimensional succubus bloodline being discovered.]
"A system mission? Perfect timing."
Akira slowly walked toward Freed.
The moment he called out Freed's name, he had already decided to kill him!
